SPECIFICATION forming part of Letters Patent No. 237,347, dated February1, 1881.

' Application filed June 10,1880. (No model.) I

To all whom it may concern Be it known that I, EZRA J. WARNER, of thecity of Newark,'in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Machines for MakingLacing-Studs for' Shoes, Gloves, Corsets, &c.; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

The object of this invention is to more expeditiously manufacturelacing-studs for shoes, gloves, corsets, 850., of a peculiarconstructionto wit, the studs have an eccentric neck, which connects thehead to the portion attached to the glove, &c. This part of the stud(the portion attached to the glove, 850.) is formed of two plates, whichare also connected together by a neck, said neck being, however,concentric. It will be seen, therefore, and especially so by referenceto the illustration, Figure 5 of the drawings, that the stud which Idesire to manufacture by my invention has both an eccentric andconcentric neck or shank.

Heretofore studs of this character have been made by hand, which processor operation has been attended with so much difficulty and ex pense asto practically exclude the article from the market. By my invention,however, this difficulty has been entirely overcome, so that thearticles can now be manufactured expeditiously and perfectly at acomparatively trifling expense.

The invention consists in the combination of means for turning, by acontinuous opera tion, from a solid wire or rod, a stud having aneccentric and concentric neck thereon.

It further consists in means for automatically supplying the said solidwire or rod to the said means for cutting the eccentric and concentricneck upon said stud.

It still further consists in the combination of means for automaticallybringing the cutters successively to bear upon the wire with means forautomatically changing its center of revolution while still in motion;and it finally consists in the further combination of parts,

as will hereinafter be more fully set forth and claimed.

Referring to the accompanying drawings, in which similar letters ofreference indicate like parts in each of the several figures,Figure 1 isa plan view of my invention, showing the relation of the different partscomposing it to one another; Fig. 2, a'perspective view of the leverwhich is operated upon by the cam B to actuate the sliding plate f. Fig.3 is an end elevation, as indicated by the arrow in Fig. 1 and Fig. 4.is an enlarged section taken through line no of Fig. 1, which more fullyillustrates the manner of changing the center of revolution while themachine is in motion and Fig. 5 is a view of the stud which myinvent-ion manufactures, showing the eccentric and concentric neck orshank.

In carrying out my invention, I first construct upon the table orbed-plate the head and tail pieces, M and M, which carry thehollow shaftor mandrel N. This shaftis actuated in its rotatory motion by powerreceived from the driving-shaftin g through the pulley 0.

To the end of the mandrel N is attached the chuck 1?, Figs 1 and 4,which is perforated and grooved to receive the levers e and the slidingplates f. The chuck P is also adapted to receive the sliding cam B,which revolves with it. This cam is so constructed, Fig. 4, thatit can,by changing the point of contact with the lever e, or the set-screw 01therein, change the center of motion of the sliding plates f, and inconsequence the wire 2, heldin the embrace of said sliding plates f. Thesliding cam B is actuated in its lateral movement, substantially as inthe manner shown in Fig. l, by thelever A, which receives such motionfrom the grooved cam B upon the shaft 1).

The wire from which the buttons are manufactured is fed to the cuttersby means of the spring-clutch r,t he jaws of which pass through theshaft and clutch the wire. Said jaws are adapted to slide over the wirein the backward motion, but to hold and carry said wire in the forwardmotion. The clutches are held upon the wire by the spring 8, work uponthe pivots t, and are actuated in their backward and for- Ward motion bythe lever A,which works upon the fulcrum E, and is, in turn, actuated bythe grooved cam (3 upon the shaft D.

The mechanism for operating the cuttingtools is driven by the pulley andshaftin g D and D, which work in the bearings F. The cutters g are heldin the tool-posts E, which are adjusted in the grooved cutter-carrier K,which works in the saddle L. Said cuttercarrier Kis connected with andoperated by the cam H upon the shaft D. By means of this cam H the toolsor cutters g are alternately brought to bear upon the wire in a mannerin itself common.

In operating the invention, the wire 2: being properly supplied to thehollow mandrel and the machine set in motion, the feeding mechanism,already described, supplies the requisite quantity of wire for a button.The cam B will then, by means of the lever A, throw the eccentricportion of the cam 13 into contact with the set-screw d of the lever e,which action will change the center of revolution of the plates f,sliding in the chuck P,and with them the revolving wire held therein. Atthis moment one of the cutters is brought to bear, by means of the camH, upon the said wire, and the eccentric neck or shank is turnedthereon. The tool which thus cuts the eccentric neck then passes backfrom engagement with the wire, and at the same time the second cuttercomes into engagement with the wire 2, which wire has, however, in themeantime (by means of the cam B, the lever A, the sliding cam B, thelever e, and the sliding plates f) changed its center of revolution backto its normal position, and a concentric neck is thereby out into thewire. At the same time the head of the stud is finished and the buttonis cut from connection with the wire and drops into a receptacle below.It should here be mentioned that the sliding cam B is so formed that atthe moment that the clutch throws the wire forward the said sliding camB causes one of the levers to slightly open one of the sliding plates,and thus to leave a passage for the wire 2. All these operations areperformed and repeated by a continuous movement of the machinery, andafter being at first properly regulated and adjusted it requires nofurther manipulation by an attendant, except, of course, in so far as tosee that the wire is properly supplied to the machine.

Having thus described my invention, what I claim, and wish to havesecured by Letters Patent, is-

1. In a machine for cutting an eccentric and a concentric neck to a wireor rod, the combination of a hollow revolving mandrel, as N, forcarrying the wire, a chuck, as P, at the end of the mandrel, providedwith sliding plates, as f, a cam and levers, as B and e, for slidingsaid plates back and forth, cutters, as g, for cutting the necks, andmechanism for imparting motion to the several parts, substantially asset forth.

2. In a machine for cutting an eccentric and a concentric neck to a wireor rod, the combination of mechanism for revolving and automaticallyfeeding forward said wire, and sliding plates, as f, for moving saidwire, substantially as described, in order that it may be operated on bycutters, as 9, so as to have cut therein eccentric and concentric necks,sub-" stantially as set forth.

3. In a machine for cutting an eccentric'and a concentric neck to a wireor rod, the combination, with mechanism for revolving and feedingforward the Wire, of sliding plates, as f, for moving the wire,substantially as described, and a carrier, as K, for bringing thecutters alternately against the wire, so as to cut the necks,substantially as set forth.

4. In a machine for cutting an eccentric and a concentric neck to a wireor rod, the combination of mechanism for revolving and automaticallyfeeding forward the wire, sliding plates, as f, automatically movingsaid wire so as to be operated on by cutters, and a carrier, as K,automatically bringing first one cutter and then another against thewire, whereby eccentric and concentric necks are automatically formed inthe wire, substantially as and for the purposes set forth.

5. In a machine for cutting an eccentric and a concentric neck to a wireor rod, the combination of levers A and A, cams O and B, shaft D,sliding cam 13, clutches r, and platesf, the several parts being adaptedto operate substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this26th day of May, 1880.
